Historically, Decware is slow to get updated material on the web, and I'm not sure I ever had a manual in the box with a component, just one of those idiosyncratic things. You may want to email or call Sarah and ask about an updated manual.

I emailed Steve, no response yet, I do realize he's a busy guy.I figured out most of what I need to know, so I don't really need the manual anymore but others will.

Again, providing wrong dimensions for the product on its own support page? Not specifying which inputs are which, not mentioning that the "direct" input will also be attenuated when the volume know is turned all the way to the left? For all I know this could be a defect.

"Slow to get updated material on the web" - documentation should be ready before the product is sold.

As Lon says, this is one of "those things." I am a ZS owner also. I bought the amp specifically to power my center channel speaker in my combo audio/HT rig. To this day, I am not 100% sure I have it hooked up correctly for mono bridging a single channel of audio into a single speaker with the full power capability of the amp. I think I have it right, but am not completely sure. My ZS has a switch installed for bridging, and it's not directionally labeled; another one of those quirks. So, I sympathize with meraklya. All things considered, I am very happy with my Decware, but this is one little area that could be better.

- Inner RCA pair (closest to the power cord): direct input, not affected by volume control unless it is turned all the way to the left, towards the end of the travel the signal will be rapidly attenuated and then shut off- Outer RCA pair: variable input, affected by volume control- Physical depth of the product is 14.75 inches, not 12 inches
